Safety Precautions

Warning!
Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections
while the power is on. Sensitive electronic components can be
damaged by sudden power surges. Only experienced electronic
personnel should open the PC chassis.

Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all electronic components
in a static-dissipative surface or static-shielded bag when they are
not in the chassis.

Installations
2.1 Memory Module(SO-DIMM)Installation
The ID31 Motherboard provides one 204-pin SODIMM slot. The socket supports up
to 4GB DDR3 1066 SDRAM. When installing the Memory device, please follow the
steps below:
Step.1. Firmly insert the SO-DIMM at an angle into its slot. Align the SO-DIMM on
the slot such that the notch on the SO-DIMM matches the break on the slot.
Step.2. Press downwards on SO-DIMM until the retaining clips at both ends fully
snap back in place and the SO-DIMM is properly seated.

Caution!
The SO-DIMM only fits in one correct orientation. It will cause
permanent damage to the development board and the SO-DIMM if
the SO-DIMM is forced into the slot at the incorrect orientation.

2.2 I/O Equipment Installation
2.2.1 12~24V DC-IN
The Motherboard allows plugging 12~24V DC-IN jack on the board without another
power module converter under power consumption by Intel Atom N2600 1.6GHz
Processor in NM10 chipset.
2.2.2 Serial COM ports
Two RS-232 connectors build in the rear I/O. One optional COM ports support
RS-422/485. When an optional touch-screen is ordered with PPC, serial com port can
connect to a serial or an optional touch-screen.
※Without power/reset OSD, you can short circuit pin5 & 6 of the onboard panel
connector to boot up the motherboard.
2.2.3 External VGA
The Motherboard has one VGA port that can be connected to an external CRT/ LCD
monitor. Use VGA cable to connect to an external CRT / LCD monitor, and connect
the power cable to the outlet. The VGA connector is a standard 15-pin D-SUB
connector.
2.2.4 Ethernet interface
The Motherboard is equipped with Broadcom BCM57780 chipset which is fully
compliant with the PCI 10/100/1000 Mbps Ethernet protocol compatible. It is
supported by major network operating systems. The Ethernet ports provide two
standard RJ-45 jacks.
2.2.5 USB ports
Four USB devices (Two with pin headers) may be connected to the system though an
adapter cable. Various adapters may come with USB ports. USB usually connect the
external system to the system. The USB ports support hot plug-in connection.
Whatever, you should install the device driver before you use the device.
2.2.6 Audio function
The Audio 7.1 channel capabilities are provided by a Realtek ALC886 chipset
supporting digital audio outputs. The audio interface includes two jacks: line-in and
line-out.

2.4 Jumper Setting
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
The jumper setting diagram is as below. If a jumper shorts pin 1 and pin 2, the setting
diagram is shown as the right one.

ID31 Motherboard User Manual /
Engineering Spec.
Chapter 7 AMI BIOS SETUP
Your computer comes with a hardware configuration program which called BIOS
Setup that allows you to view and set up the system parameters.
The BIOS (Basic Input / Output System) is a layer of the software called ‘firmware’
which translates instructions from software (such as the operating system) into
instructions that allow the computer hardware to understand the software programs.
The BIOS settings also identify installed devices and establish many special features.
ENTERING BIOS SETUP
You can access the BIOS program just after you turn on your computer. Just press the
“DEL” key when the following prompt appears:
Press <DEL> to enter Setup.
When you press <DEL> to enter the BIOS Setup image, the system interrupts the
Power-On Self-Test (POST).
When you first enter the BIOS Setup Utility, you will enter the Main setup image. You
can always return to the Main setup image by selecting the Main tab. There are two
Main Setup options. They are described in this section. The Main BIOS Setup image
is shown as below.
ID31 Motherboard User Manual
44
ID31 Motherboard User Manual /
Engineering Spec.
The Main BIOS setup image has two main frames. The left frame displays all the
options that can be configured. Grayed-out options cannot be configured. On the
contrary, options in blue can be configured. The right frame displays the key legend.
Above the key legend is an area reserved for a text message. When an option is
selected in the left frame, it is highlighted in white. Often a text message will
accompany it.
